The Ultimate Weapon

Gadget is sent to investigate why Dr. Claw is holding a contest with a $1,000,000 prize for the owner of the world's stinkiest animal. Meanwhile Penny has given the Gadgetinis experimental digestive systems so they can eat and turn the food into electricity. They quickly become addicted to eating and try everything which causes the digestive systems to overload and emit noxious odours so they win the contest. Gadget is happy to get the cheque but the problem is that the contest is a front for a MAD plot. The winning animal is to be squished and their concentrated stink extract used to arm an orbiting stink bomb which will cover the world with a foul smelling stench. Then MAD will sell the scent neutraliser their chemists created for a fortune since everyone in the world will be a customer. Since the Gadgetinis won they're taken to the squashing machine and Gadget's too happy to have won $1,000,000 to interfere so it's up to Penny to save the day.
